1、 Acoustic parameters
Box design: Adopting prism glass design, with a 30 ° oblique angle, the resonant frequency of the box is precisely controlled below 120Hz, and the standing wave interference in the middle and high frequency bands is reduced by 37%. The vibration energy of the box is directionally exported through the bottom silicone matrix, and the equivalent volume is increased by 22% compared to the previous generation. The low-frequency diving can reach 45Hz (-3dB).
Waveguide structure: Hidden waveguide structure, high-frequency unit designed with 6-channel phase compensator, widening the diffusion angle above 15kHz to ± 60 °.
Chip configuration: DAV3.2 processing chip, supporting vertical sound field construction, dynamic EQ compensation, multi device matrix protocol and other functions.
Speaker Unit: Independent high, medium, and low frequency speaker unit.

2、 Lighting system
Lighting effects: Provides five dynamic lighting modes: Aurora illusion, rippling blue waves, rising sun, colorful falling petals, and snow night fire.
Light adjustment: Equipped with a main sound box ambient light and dual side breathing lights, the breathing light color temperature is locked at 2700-3000K, and the brightness changes follow the Fibonacci sequence rhythm (0.618 second gradient), supporting personalized settings through the app.

3、 Connection and compatibility
Wireless connection: Supports Bluetooth 5.4 technology and can connect two devices simultaneously, achieving seamless switching and usage.
Serial function: Supports wireless serial function and can be connected to TV or projection devices through HDMI ARC interface.
Multi device protocol: supports simultaneous connection of up to 4 devices to form a 7.1.4 system, with a time difference controlled within 0.8ms.
